结垢和微生物粘泥及伴生的腐蚀故障,对冷却水系统的安全、正常和运行影响极大。因此需要定期进行清洗,通过安全有效的化学清洗可达到如下目的:1安全正常运行,显著提高设备冷却效率;2减低运行成本,节约能源;3改善水质,保护设备金属,延长设备使用寿命。4预防“军团菌”感染,保障人们健康。通常冷却水系统用水是未经处理的自来水,主要问题是由于管道腐蚀较严重,水质呈锈红色,换热设备由于有粘泥等沉积物附着,影响了换热,需进行清洗。清洗的目的主要是清除锈蚀和沉积物,并做好钝化预膜和解决日常防腐蚀问题。
Fouling and microbial slime and associated corrosion failures have a significant impact on the safety, normality and operation of cooling water systems. Therefore, regular cleaning is required. The safe and effective chemical cleaning can achieve the following objectives: 1. Safe and normal operation can significantly improve the cooling efficiency of equipment; 2. Reduce operating costs and save energy; 3. Improve water quality, protect equipment metal and extend equipment service life. 4 Prevention “Legionella” infection, protect people’s health. Usually cooling water system is untreated water tap water, the main problem is due to more serious pipeline corrosion, water quality is rusty red, heat transfer equipment due to sludge and other sediments attached, affecting the heat exchanger, the need for cleaning. The main purpose of cleaning is to remove rust and sediment, and passivation pre-film and solve the daily anti-corrosion problems.
